IPSEC client authentication problem

gizbri · ‎04-06-2011

ASA5520 8.2(4) Ipsec client VPN authenticating with LDAP to MS DC.

This has been up and working without issue for months. Suddenly we are getting the following message when some users attempt to login:

Apr 06 2011 15:33:02 Group = VPN, Username = jdoe, IP = x.x.x.x, Remote peer has failed user authentication - check configured username and password

The username and password are proven good both in the MS network and when doing a AAA test on the ASA.

This is not happening to all users.

I did find some info about Kerberos and checking this in the AD Account: Do not require kerberos pre-authentication

Modifing this did not help.

Any ideas?

Thanks

Check the use for password about to expire. I have seen that a bug, if the password is about to expire it will fail the user authentication web though the AAA test works.

Hi,

Could you please try the following:

test aaa authentication host < ip address of AAA server> .

Please paste the output of "sh run aaa" and "sh run tunnel-group "

hope this helps.

Anisha

t.j and Anisha - thnaks for the response.

t.j. - it doesnt appear we're hitting that bug

Anisha - test from ASA works fine.

What I am finding is the problem appears to be affecting certain hosts, not accounts. My account , for example, works fine on one PC , yet fails with the above error on another.

We have unistalled and re-installed the VPN client and it does not help.

Here is a log of a failing VPN client.

hi,

You are right. The problem is not with the account.

The debugs clearly state the reason for delete is authentication failure.

could you please check that the password types is correct. i.e. no spaces are entered. Also are any of the other users able to connect to the client from this server?

please let me know the OS of the client.

Regards,

Anisha

gizbri · ‎04-11-2011

password is correct. I have a different laptop next to me and authentication works fine using the same account. This is affecting only a few users, all others are funtioning normally.

andamani · ‎04-12-2011

Hi,

This seems to be a hardware issue. It looks like the laptop is entering "space" in between the alphabets of the password.

Could try using an extended keyboard and test?

If this still not works then, please try uninstall and re-install of the client from your laptop.

Hope this helps.

Anisha
